Discussion Forum : Number Series - Type 1 (Q.No. 1)
Directions to Solve

1.
Look at this series: 2, 1, (1/2), (1/4), ... What number should come next?
Answer: Option
Explanation:
This is a simple division series; each number is one-half of the previous number.
In other terms to say, the number is divided by 2 successively to get the next result.
4/2 = 2 2/2 = 1 1/2 = 1/2 (1/2)/2 = 1/4 (1/4)/2 = 1/8 and so on.

2, 1, 1/2, 1/4, ?......2, 1, 0.5, 0.25.
See that series clearly know divided by 2, get next number.
So, 0.25/2 = 1/8.

Suppose that it is 2, 1, (1/2), (1/4).
Than we can easily understand by doing this in this way.
Second number multiplied from first number and then get the next number.
Like: 1/2 * 1/4 = 1/8 solved.
